Sehlopha sa bauxite
Bauxite, eo hape e tsejoang e le bauxite kapa bauxite, haholo-holo e entsoe ka aluminium oxide 'me e na le litšila. Bauxite e na le sebopeho se rarahaneng haholo 'me ke lentsoe le akaretsang bakeng sa mefuta e fapaneng ea li-alumina tsa hydrous tse nang le tšimoloho e fapaneng haholo ea jeoloji.
Ho ea ka tšebeliso ea bauxite, e arotsoe ka metallurgical grade, chemical grade, refractory grade, grinding grade, samente kereiti, joalo-joalo E sebelisoa ho etsa thepa refractory, mofuta ona oa bauxite bitsoa refractory grade alumina. Bauxite clinker e nang le likarolo tse loketseng tsa AL2O3/Fe2O3 le AL2O3/SiO2 e sebelisetsoa ho qhibilihisa alumina.
1. Mocheso o phahameng oa refractory, botsitso bo matla ba mocheso, 'me ha ho na ho phunyeha. Aluminium mullite sand ke sehlahisoa se thehiloeng ho aluminium-silicon. Ka mor'a calcination, refractoriness ea eona le mocheso oa ho sisinyeha ha mocheso li kholo haholo ho feta tsa lehlabathe la quartz le nang le sebopeho sa kristale se entsoeng ka silicon e le 'ngoe ea kristale. Ha e kolobisoe habonolo ke tšepe ea mokelikeli ho etsa mokelikeli o tlase, o ka hlolang lehlabathe la Quartz le na le coefficient e kholo ea katoloso ea mocheso le chai e mpe nakong ea condensation, e bakang mefokolo joalo ka ho nepahala ho tlase le ho khomarela lehlabathe.
2. Phapang ea likaroloana tse fapaneng, phefumoloho e ntle. Lehlabathe la Foundry le siloa ke leloala la Raymond 'me le tsoakoa ho ea ka karoloana e itseng nakong ea tlhahiso ho ntlafatsa ho kenella ha moea oa pente. Ho feta moo, lihlahisoa tse entsoeng ka li-mill tsa bolo, likaroloana tsa lehlabathe tse entsoeng ke Raymond li laoloa hamolemo, 'me karolo ea bauxite clinker ke saense haholoanyane.
3. Liaparo li na le fusion e phahameng, matla a phahameng le ho senya habonolo. Liaparo tse fapaneng tsa refractory li sebelisa lihlahisoa tsa aluminium-silicon clinker, tse lahlehileng foam bauxite clinker phofo e ntle, ho latela likaroloana tse fapaneng tse tsoang kahare ho tsoa. Motsoako ho tloha ho o motle ho ea ho o mobe o fella ka tekanyo e phahameng ea ho kopanya pakeng tsa liaparo; ha a ntse a eketsa matla a ho roala le ho hanyetsa khoholeho ea mobu ho thibela mathata a kang ho oa, ho boetse ho bonolo ho e etsa. 'Me bauxite mullite ke ntho e sa nke lehlakore, 'me bauxite clinker e ka sebelisoa e le li-binders tsa asiti le alkali.
